I want to make sure I'm 100% right as to the reason you see multiple files
with IO so I'll answer that shortly.

As for hard disk noise, this happens whenever you do a lot of read/write on
your disk, especially moving files around physically (versus moving them
from c:\users\me\documents to c:\users\me\pictures). When you download
large files or install big programs you will hear disk noise from the
hardware moving. Hard disks have a lot of moving parts. The spinning of
the spindle assembly, and seek movements of the head actuator (which has
lots of moving parts all on its own), are probably the noises you're most
aware of...

Defrag moves files around a LOT, so you get a lot of this hard disk IO noise
the whole time you defrag.
